IANA zones · the technical identifiers
The zone that resolve to WGST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about WGST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- When does West Greenland observe daylight saving time?
- From late March to late October, when Nuuk moves from its standard UTC-02:00 to UTC-01:00; clocks go back to -02:00 at the end of October.
- Why did Greenland’s time change in 2023?
- In March 2023 Nuuk and most of Greenland moved their standard time from UTC−03:00 to UTC−02:00, one hour closer to Europe. They skipped the autumn change that year and began using summer time (UTC−01:00) in March 2024.
- Which parts of Greenland use West Greenland Time?
- Nuuk and the populated west coast, including Sisimiut and Ilulissat, where most Greenlanders live. Pituffik (Thule) in the northwest uses Atlantic Time instead, and Danmarkshavn on the northeast coast stays on UTC+00:00 all year.
- How far is Nuuk from Copenhagen?
- Three hours behind all year. Both switch to summer time on the same dates, the last Sunday in March and the last Sunday in October.
